What is responsive web design?

Your website is accessed on a host of hand held devices other than a desktop or a laptop. Each device has a different display size.
The smartphone is 320px and 480px, iPad is 768px and 1068px, and then there is a width, usually taken as greater than 1068px.
Web content is expected to render itself suitably to enhance user experience on each of these devices. Such web content that looks good on all devices is said to be responsive web design. The webpage or the website responds, and automatically adjusts to the screen size.

Responsive design using CSS

Responsive websites use CSS (Cascading Style Sheets) to automatically resize – enlarge, shrink or hide sections to look good on devices of all sizes.
You can modify the CSS to accommodate varying screen sizes. Use a meta-tag called “viewport” in the HTML file to give instructions to the browser on how to control the page’s dimensions and scaling.
Similarly, you can use controls for images as well as text size to make the websites responsive.
For images, use width=100% and max-width=100% depending on the exact requirements.
For making the text size responsive, set the text size with a “vw” unit, which means the “viewport width”.

Does web browser make a difference?

It is worthwhile to point here that there are different web browsers, and websites render differently in each web browser too. The most common web browsers in use are:

  • Google Chrome
  • Mozilla Firefox
  • Apple Safari
  • Opera
  • Microsoft Edge

With web technology constantly changing and evolving, it becomes necessary to check-up on the responsiveness of your website design at least quarterly. This gives you an opportunity to identify if there are any responsive issues with your website and make necessary modifications.
